Blockchain Design Choices for Healthcare Data Sharing

Healthcare blockchain initiatives need careful architecture because immutable records, patient privacy, interoperability, and regulatory obligations can conflict if data models are poorly designed. The article explains use cases including EHR access, consent management, clinical trials, medicine authentication, payments, insurance, telemedicine, and supply chain traceability. It also highlights implementation constraints around scalability, standards, HIPAA/GDPR compliance, technical expertise, interoperability, cost, and human error. Technology leaders should assess blockchain as a selective trust and auditability layer, not a default replacement for healthcare data platforms.
